More on making copper wind vane

Copper work hardens, but how fast. If my friend was hammering copper to
"sculpt" it, how much depth/stretch could he do before it would have
to be annealed? To avoid cracking. I'd guess that it depends upon the
thickness of the copper, so is there a multiple of the thickness that he
could use as a rule of thumb?
